Revision Standard - Superseded. Methods for qualifying static battery chargers and inverters for Class 1E installations outside containment in nuclear power generating stations are described. These methods may also be used to qualify similar electronic equipment for use in applications outside containment, where specific standards for such equipment are not available. The qualification methods set forth employ a combination of type testing and analysis, the latter including a justification of methods, theories, and assumptions used. These procedures meet the requirements of IEEE Std 323-2003.
This standard describes methods for qualifying static battery chargers and inverters for Class 1E installations outside containment in nuclear power generating stations. The application of this equipment in the plant's electrical system is not within the scope of this standard as other industry standards, such as IEEE Std 308TM-2001 [B3],1 IEEE Std 603TM-1998 [B6] and IEEE Std 946TM-2004 [B8], exist for this purpose. In addition, industry standards exist for equipment performance, such as ANSI/NEMA PE 5-2003 [B1] and IEEE Std 944TM-1986 [B7]. Performance requirements are not specified in this standard.
The purpose of this standard is to provide specific procedures to meet the requirements of IEEE Std 323TM-2003.2 For the purpose of this standard, battery chargers, inverters, and the associated ancillary equipment must perform their safety function under specified service and environmental conditions. The demonstration that an installed battery charger or inverter will meet its design specification requires many steps in a program of design, fabrication, quality assurance, qualification, transportation, storage, installation, maintenance, periodic testing, and surveillance. This standard treats only the qualification area of this program. The result of the qualification program may provide a basis for determination of long-term maintenance requirements. Qualification may be accomplished in several ways: type testing, operating experience, or analysis. These methods may be used individually or in combination. The qualification methods in this standard employ a combination of type testing and analysis. Operating experience is of limited use as a sole means of qualification. Operating experience is, however, of great use as a supplement to testing, as the experience may provide an insight into the change in behavior of materials and components through time under actual service and maintenance conditions. Qualification by analysis shall include a justification of the methods, theories, and assumptions used. In general, battery chargers and inverters are too complex to be qualified by analysis alone, although analysis is effective in the extrapolation of test data and the determination of the effects of minor design changes to equipment previously tested.
